11 Claims.

This application relates in general to time measuring apparatus, and more particularly to that type of apparatus designed for measuring the time which a vehicle remains parked in a given location.

Great dii'liculty has been encountered from time to time in regulating the parking on the city streets, and in other locations. and various means have been devised for regulating this practice in such a manner that the public would derive the greatest benefit from the parking space available, and would not unduly hamper tramo. One means of controlling the parking of vehicles has been to provide a meter or time keeper ll which will indicate to a passer-by upon a mere casual inspection the length of time which has elapsed since a vehicle was parked in the space controlled by said device.

It is an object of this invention to provide a A device of this general character which will elimi- .nate the diillculties encountered by and inherent in previous means for this purpose.

It is a more speciilc object of this invention to provide a device which will indicate at a glance whether or not a given period which has been paid for has expired, and which will show on inspection within certain limits the length of time which has expired beyond the period within which parking is allowed.

`It is a further object to provide a device of the character set forth in which when the device is to be reset before the initial period has expired, a signal will be operated to indicate that the time period has expired, and this signal will not be rendered inoperative until the resetting operation is complete.

It is a further object of this invention to provide a device ci' the character set forth with a signal adapted to indicate that the allowable o parking period has expired, and to eliminate the necessity in such a device for a latch or catch mechanism to hold such signal in inoperative position until the time has expired.

One other object of this invention is to provide a device of the character described which will give a readily perceptible visual indication o! whether or not the time has expired, and will give this indication at night as well as in daylight.

Another object is to provide a device which will give an accurate indication of the passage o! time after the allowed parking period has expired, as well as prior thereto.

Another object is to provide a separate scale upon which overtime parking is indicated, and

u to provide for the automatic replacement of the (Cl. IGI-15) Fig. 1 is a view partly in vertical cross section showing in front elevation the working parts of a device constructed in accordance with this invention.

Fig. 12 is an end view of theresetting arm shown in Figs. 10 and 11 with a coin in place therein after -the resetting operation has begun.

Fig. 13 is a view partly in'vertical vcross section illustrating details of the resetting arm.

Referring now moreparticularly to the drawings, there is illustrated in Figs. 1 and 2 a housing for the device having an upper and somewhat larger portion I and a lower relatively narrow portion 2. The upper portion of this housing (see Fig. 4) is provided in its opposite faces with similarly disposed windows 3 through .which the time-indicating parts may be viewed, and with display windows 4 which may -be utilized for any' desired purpose such as for giving instructions for the use of the device.

In the front face of the enlarged upper portion I (Fig. 4) there is provided an opening 5 of a size suillcient to receive and permit the passage of the knob or operating handle 6 (see Fig. 1). Just above the operating handle 6 there is formed a slot 1 in the support plate 8 in which the operating handle is journalled. This slot 1 is for the reception of a coin in those instances where the device is employed for the purpose of exacting the payment of a given amount before the resetting mechanism can be actuated.

In alignment with the front window 3 (Fig. 4) the support plate 8 carries a scale 8 graduated in units of time and adapted to provide a means upon which the passage oi' time is indicated prior to the expiration of the allowed parking period. A similar scale I8 is mounted in an opposed position directly behind the window 3 in the rear wall of the housing, the purpose of this second scale being to permit the reading of the meter from either side thereof.

Within the tapered lower portion 2 of the housing (see Figs. 1 and 2) there is provided space for the coin box II adapted to receive the coins dropped into the device, this box having a slot I2 therein through which the coins pass into the box, and a sliding door I3 therein for the removal of the coins from the box. Suitable provision may be made for the sealing of this door, if so desired. The coins are conducted downwardly from the meter proper by means of a coin chute I4 (see also Fig. 3) so positioned that coins will drop therefrom directly into the slot I2 in the coin box. This chute I4 is provided with an ear or similar means I5 by which it may be attached to the inner wall of the housing.

Referring again to the details of the time-indicating structure and resetting mechanism therefor, it will be seen that in addition to the front support plate 8 already referred to', there is a second rear support plate I6, (see Figs. 2, 3 and 4) thesel plates being joined together by means of posts I1, two of which are extended to form a support for the rear dial or scale I8.

As has already been stated, the handle 6 is journaled in the support plate 8, and rearwardly of the support plate (Figs. 3 and 4) is provided with an operating arm I8 fixedly mounted with respect to the handle 6 so as to rotate therewith. The pin I9 or similar connection is provided for fixedly mounting the arm I8 upon the inner endl of the operating shaft carried by the handle 6. The operating shaft and handle, together with the operating arm I8, are normally urged in a counter-clockwise direction, as one faces the meter, by means of a spring 28 (Fig. 3) anchored to the plate 8. The arm I8 is thus normally held in its uppermost vertical position (Fig. 5) against a suitable stop provided therefor. In this position, the slot in the operating arm I8 is held in alignment with the slot 1 in the plate 8 so that a coin inserted through the 'slot 1 will be passed into the slot in the operating arm I8.

Slidably mounted on pins 2|, or similar supports, there is shown in Figs. 5 and 6 a plate 22 having a downwardly extending portion 23 adapted when the resetting arm I8 is moved toward resetting position (see Fig. 6) to partially cover the slot 1 in the plate 8 and prevent the insertion of a coin therethrough. This downwardly extending portion 23 has a lug 24 theren adapted to be contacted by the arm I8 when said arm is in its uppermost position as shown in Fig. so that the plate 22 will .be pushed by the arm I8 against the tension of the spring 25 until the portion 23 uncovers the slot 1.

Mounted on the rear surface of the plate 8 (see Figs. 3, 5 and 6) with the center of rotation of the arm I8 as its center is a segmental track 28 having ratchet teeth 21 formed thereon. Arranged along the outer edge of this track is a retaining shield 28 for a purpose which will be presently described. The track 26 at its leading edge is bevelled as -shown at 29 in Figs. 6 and 12, and it will be seen that when a coin is inserted through the slot 1 into the slot in the arm I8, and the arm I8 then rotated, the coin will be caused to ride up the inclined portion 28 of the track 26 and thence to ride along this track until the end of the track is reached. Such a coin is illustrated in Fig. 12 at 38, and it will be seen that when it rides up on the inclined surface 28 it will move the resetting member 3i in an axial direction away from the plate 8. 'I'his resetting member 3I has lugs 32 and 33 thereon. the purpose of which will presently appear, and this member is constantly urged toward the plate 8 and the arm I8 by means of springs 34 (Fig. 13) Also, pivotally mounted on one side of the arm I8 (see Figs. 10 and 12) is a pawl 35 pivoted at 36, and having a spring 31 constantly urging the end of said pawl in a direction to engage the ratchet teeth 21. This pawl is normally held out of engagement with such teeth by means of the member 3|, (see Fig. 10) thereby permitting free rotation of the handle. When, however the member 3I is moved axially by the insertion of a coin and the rotation of the operating handle to the position shown in Fig. 12, for example, the pawl 35 will be released to engage with the teeth 21 as clearly appears in that figure (see also Fig. 3).

Journaled in the rear support plate I6 as shown in Figs. 7, 8 and 9 is the main operating shaft 38, a bridge 38 anchored to the plate I6 as shown at 48 (see also Fig. 3) being provided for the purpose of furnishing extra support for the shaft 38. Fixedly mounted on this shaft for rotation therewith is an arm 4I carrying the timeindicating hand 42 on one end thereof in a position to move along and over the scale or dial 8 to indicate the passage of time (Fig. l). This hand, together with the shaft 38, are normally urged toward the zero position on the dial by means of a spring 43, this spring being of insumcient strength, however, to prevent the movement of the hand over the dial from the zero point to indicate the passage of time. Also ilxedly mounted upon the shaft 38 in a position spaced axially from the arm 4I is a second arm 44, (see Figs. 3 and 4) this arm lying closely adjacent the support plate I6, and carrying at its outer end a hand or pointer 45 similar to the pointer 42. It will be seen that since both of these arms and pointers are iixedly mounted on the shaft 38, they will move in unison as the shaft 38 is rotated.

Rearwardly of the plate I6 as shown in Figs. 3 and 4 the shaft 38 is provided with a gear 46 meshing with a second gear 41 which is in turn mounted upon the main shaft of a time-keeping mechanism 49 of any conventional character desired. 'I'he mechanism 45 is shown as being secured to the plate I by means' oi' bolts 45 or the like, (see also FIg. 2) and is provided with a means 50 for the reception of a key whereby the pointers 42 and 45 may be manipulated forpurposes of repair or adjustment. It is contemplated that in the event a spring-operated mechanism is employed, the spring will be given an initial wind tofa predetermined degree, and that thereafter the resetting of the pointers 42 and 45 in starting the meter, as more fully appears hereinafter and the consequent rotation in a reverse direction of the shaft 55 will serve to rewind the spring of the clock mechanism and render It unnecessary for this mechanism to be separately wound.

Freely rotatable upon the shaft 55 between the arms 4I and 44 (see Fig. 3) is an arm 5| carrylng flags or signalling devices 52 and 55. These flags are so positioned that when the arm 5I is moved in a counter-clockwise direction, as seen in Fig. 7 the flags will move to a position overlying and substantially concealing the dials 9 and I5. It is contemplated that these flags shall be of some distinctive color different from the color of the dials 5 and I5. so that when the flags are covering the dials this will be readily apparent even on a cas'ual inspection. The ann 5| is normally urged in a clockwise direction so as to position the fiags52 adjacent the top of the mechanism as shown in Figs. 1. 2 and 9 and uncover the dials 9`and I5, the force urging this motion of the arm 5| being supplied by the spring 54 which is of suilicient strength to raise the flags 52 and 55.

At its end opposite the flags 52 and 55. the arm 5| is shapedas shown at 55 (see Fig. 8) to coopcrate with and beretained by the latch member 55. This latch member is normally urged into engagement with the arm 55 by means of a spring 51, and is provided with a laterally extending cam-shaped part 55 (see also Figs. 3 and 4) for a purpose which will presently appear. The movement of -the latch 55 toward the end 55 of the arm I5| is limited bycmeans of a pin 59 shown clearly l' mounted on the end of the arm 55 and urged into engagement-with the arm 55 by means of a spring 54. This arm 55 is'ada'ptedto abut a lug 55 on the portion 55 of the arm 5| andmove arm 5I counter-clockwise intoits latched position as seen in Figs. 7 and 8 upon release of latch 52, thereby kbringing signal flags 52 and 55 into signailing position.

Mounted on the arm 55 which carries the latch 52 is an adjustable cam-shaped lug 55 so positloned that when the shaft 55 has rotated a predetermined'distance and the hands 42 and 45 have indicated the passage of a predetermined length of time, the end of the arm 4I opposite the hand 42 (see Fig. '1) vwill engage the cam element 55 and will cause the latch 52 to release the arm 55 raise arm 5| and'drop signal flags 52 and 55 into signalling position as noted above. The latch 52 is provided with an inwardly projecting part 51 for a purpose which will be presently described.

Referring again to Figs. 5 and 6, there is illustrated adjacent the path of the arm I 5 as it rotates in the resetting operation, a cam-shaped element 55 mounted on an arm 59 pivotally sup-- ported at 15 on the plate 5. At its lower end, this arm is provided with a hook or catch 1I projecting into the coin chute I4 so as to retain within this chute the last coin inserted in,

the machine. 'Ihe inward extension 51 on the latch 52 (see Fig. 4) is so positioned as to be in contact with the cam-shaped member 55 or a portion thereof, and when the arm I5 is rotated with a coin in place in the slot thereof, the element 12 of the resetting member 5| will rotate the cam-shaped member 55 and cause the movement of the arm 69 to release the coin being retained in the coin chute. At the same time. this movement oi' the cam-shaped member 55 will cause a movement of the arm 55 to release the latch 52 from the arm 55, thus permitting counter-clockwise rotation of this arm thereby causing upward movement of arm 5| and a showing of the signals 52 and 55.

While a coin is being retained in the coin chute by the catch or hook 1I, such coin is also prevented from being fraudulently moved upwardly and out of the coin chut by means of the element 15 which is clearly illustrated in Fig. 3 of the drawings.

The arm 59 is normally urged to a position in which the catch 1i would retain a coin by means of a spring 14 secured thereto.

A counter 15 (see Figs. 3 and 4), is preferably mounted upon the rear surface oi' the plate I5, and the operating arm thereof which is shown at 15 extends through an aperture in said plate to be actuated in a manner now to be set forth.

In operation, a person who has parked a vehicle in a space controlled by a device constructed in accordance with this invention such as that just described, will insert a coin of the proper denomination through the slot 1 (Fig. 1) and into the slot in the resetting arm I5 (Fig. 4). He will then rotate the operating handle 5 to the right as he faces the device.` As soon as rotation is begun, the plate 22 (Fig. 5) will be moved under the action of spring 25 to the left as illustrated in Fig. 5, so as to partially close the slot 1 and prevent the insertion of another coin until the arm I5 has been returned to its initial position.

The first movement of the arm l5 also causes the coin to ride up on the inclined portion 29 of the track 25 (Figs. 6 and 12), and to thereafter ride along this track, in which position it will maintain the resetting member 5| in the position illustrated in Fig. 12. When this resetting member is in this position, it permits the pawl 55 to engage with the ratchet teeth 21 (Fig. 3) and prevent backward movement of the arm i5. Also, it moves the lugs 52 and 55 and the element 12 in an axial direction so that further rotation of the arm I5 will cause the lug 55 (see Figs. 3 and 4) to engage with the counter lever 15 and actuate the counter 15 which records the number of times the device is actuated.

Further rotation of arm I5 causes the element 12 (see Fig. 6) to strike the cam-shaped member 55 and move the lever 59 to the left as shown in Fig. 5, thus releasing the coin which has been up to this time held in the coin chute, and which was previously inserted in the machine, and simultaneously, if the arm 55 is being held by the latch 52, it will be released therefrom. (This would only occur in the event that the time for which the meter had been previously set had not yet expired and the flags were in their uppermost or non-signalling positions.) Upon release of the arm 60, if these flags were in their uppermost position, the spring Si would cause counter-clockwise rotation of the arm SG as shown in Fig. 9, and due to the presence of the lug 65 this' arm in rotating would carry with it the arm 5i upon which the flags 52 and 53 are mounted. This is due to the fact that the spring 6i is stronger than the spring 55, the spring 5d being by this action stretched until the end 55 oi the arm 5l is engaged by'the latch 56 as seen in 8. (It will be understood that if prior to resetting the mechanism the time allowed for parking has expired, the arm 5i and the ags 52 and 5t tcgether with the arm 6E will already have been rotated in a counter-clockwise direction to the position illustrated in Fig. 7 as appears more fully below.)

Upon further rotation of the arm i8, the lug 32 (see Fig. 3) will engage the lower right hand end of the arm 4l as seen in Fig. 7, and the lug 33 will engage the arm 50 (Fig. 4) so that both of these arms will be rotated in a clockwise direction. This rotation will continue until the hand 42l has been moved upwardly to the zero point on the dial and the arm 60 has engaged the latch 62, as shown in Fig. 8. It will be appreciated that this movement of the arm stretches the spring 5l, but that this in no way affects the position of the arm 5i and signals 52 and 53 because the back part of this arm is still held by the latch 56.

At approximately the point where the hand 42 has been moved to the zero point on the dial, the coin in the slot in the arm I8 will move past the end of the track 26 (Fig. 5) thus permitting the member 3| to be returned to its original position by the spring 34, and permitting'the coin, no longer retained by the tension of the spring 34 or by the shield 21, to drop into the coin chute I4.

After the coin has fallen into the coin chute the operating handle 6 is released, and the spring 2li will return the operating handle and the arm `l8 to their original positions. In moving to the original position, however, the lug 32 (Figs. 3 and 4) will contact the cam-shaped member 58 on the latch 56 (see also Fig. 8), and will release this latch from the arm 55 so as to permit the spring 54 to rotate this arm in a clockwise direction as seen in Fig. 9 to move the ags 52 and 53 to their uppermost position uncovering the dials 9 and i0. It will be seen, therefore, that-s signal ilags 52 and 53 are exposed throughout the resetting operation, coming into signalling position in starting the resetting operation and going out of signalling position upon completing the resetting.

After the device has been reset as just described, the clock-workl mechanism 48 will operate to cause a gradual movement of the pointers A42 and 45 downwardly over their respective dials until the time allowed for parking has expired, When this time has expired, the end of the arm 4|- which is opposite the pointer 42 will strike against the adjustable lug 55 on the arm 53 (Fig. 9), thus disengaging the latch 52 from the arm 50. When this occurs, the spring 5I, being stronger than the spring 54, will cause the rotation of the arm 60 as Well as the rotation of the arm 5I in a counterclockwlse direction, bringing the flags 52. and 53 to a position overlying the dials 5 and III, as seen in Fig. '7. The clock mechanism will, however, continue to run and indicate overtime operation until the pointer 42 has reached the extremity of its travel. Since the flags 52 and 53 have dials provided thereon, it will readily be seen that the pointers 42 and 45 will continue to register the passage of time, even after the time permitted for parking has expired.

It is-contemplated by this invention not only that the time-indicating means including the ags 52 and 53 shall be of a distinctive color and different from the color of the time-indicating means including the dials 9 and i0 so that overparking maybe easily detected, 'but it is also contemplated that one of the sets of dials, preferably the dials 5 and I0, shall be painted with a luminous paint, or otherwise rendered visible in the darkness, thus permitting the use of these meters after nightfall. It will readily be seen that if for instance the dials 9 and IU are painted with a luminous paint, this would by the visibility or invisibility of the radiations therefrom indicate immediately whether or not the time allowed for parking had expired.

It will be seen from the foregoing that a device has been provided which is capableof carrying out allthe objects and advantages sought by this invention.
